    labyrinth packing
    At the entrance of 1000 Pa. medium air
    The rotation of the shaft 10 000 rev / min.
    The clearance between the shaft and the labyrinth 0.15 mm

    Determine the leakage of air through the maze.
    Placed at the output of 0 Pa.
    In solving are too little speed honey shaft and labyrinth.

    Hi, 

     

    Please could you be a little more specific about the problem? I understand that you have 1000pa on one side and 0 on the other, the unit is rotating and you have a small clearance.

     

    Do you have a very good mesh through that small gap?

     

    What do you mean by 'In solving are too little speed honey shaft and labyrinth' ?

    The situation is this.
    For large shaft speed of the maze thrown oil.

    OK, those help. What about the mesh on the cut-plane? You need a good 4-5 elements though each of those gaps ideally.

     

    What is your actual question, are the results not what you are expecting to see?
